    Lac-Mégantic Rail Disaster

    In the early morning of 6 July 2013, a runaway train hauling 72 tankers filled with crude oil derailed as it approached the centre of the town of Lac-Mégantic, Quebec. The tanker cars exploded and the oil caught fire, killing 47 people and destroying many buildings and other infrastructure in the town centre. The fourth deadliest railway disaster in Canadian history, the derailment led to changes in rail transport safety rules as well as legal action against the company and employees involved in the incident. Years after the derailment, re-building was still ongoing and many of the town’s residents continued to suffer from post-traumatic stress.
